Months ago I asked for input on comparing yamaha 225hp 4stroke and the 250hp hpdi 2stoke for a 23 Parker Sport cabin deep V.

The response here and other sites was very good and appreciated.
My buddy got the boat july 2nd with the 225 4stroke. The boat rides like a dream and is nicely laid out.
I've got some numbers on fuel consumption for anyone interested:

Fully loaded the boat weighs 6,000 lbs (150gal fuel and 20 gal water + gear)

Motor Hours = 68
Gallons of fuel = 359
Average Gallons per hour = 5.28

per yamaha fuel flow management:

WOT - 6100rpm/23 gph/ 38kts gps
20kts = 10 - 11 gph (approx 4500rpm)
25kts = 13 - 15 gph

at idle, you can hardly hear the motor but at higher rpms its about the same as a 2stroke, just a different noise more like an inboard.

Thanks again

<EDIT:I had the gallons of fuel screwed up, 509 have been purchased and 150 are on the boat now, so 359/68=5.28>
